The Pyrmont Bridge was once a road bridge but has been converted to a pedestrian walkway that leads to Sydney’s Darling Harbour entertainment and shopping precinct. I knew that the bridge was a swing bridge but I was not aware that they still opened it. The day my sister and I were there this happened just as we arrived so I was thrilled to bits. We found out later that the bridge is opened regularly probably to keep the machinery in good running order in case they need to open it. It was especially interesting because the bridge carried the city monorail track over it. The monorail has since been closed so riding on that was another bit of luck.
